So, you’ve got your wet suit on, your pockets are empty, and you’re staring at the vast, blue expanse surrounding your island. It’s easy to think diving for sea creatures Animal Crossing New Horizons is just a mindless way to fill the Museum or pay off a lingering debt to Tom Nook. But honestly? Most players are doing it wrong. They’re chasing every single shadow, wasting time on Sea Grapes, and missing out on the actual strategy that turns a boring swim into a massive Bell-making venture.
You jump in. The water splashes. You see bubbles.
It feels simple, right? It isn't. Not if you want the Gigas Giant Clam.
The Reality of the Wet Suit Grind
Diving was added back in the 1.3.0 Summer Update, and since then, it’s become the backbone of many "get rich quick" schemes in New Horizons. Unlike fishing, where you’re at the mercy of your reaction time and the fragility of your fishing rod, diving is purely about stamina and knowing how to read the water. You don't need tools that break. You just need a wet suit from Nook’s Cranny or the Nook Stop.
But here is the thing: the shadow sizes are lying to you.
When you see a large shadow, your brain says "Jackpot." Then you dive, and it’s a Sea Pineapple. Again. Or a Seaweed. It’s frustrating. Expert divers don't look at the size first; they look at the movement pattern and the bubble frequency. There are three distinct speeds for sea creatures in Animal Crossing New Horizons: stationary, slow/steady, and the dreaded "I’m faster than you" sprint. If you see bubbles rising in a straight, rapid line and the shadow is darting away the moment you get close, you’ve likely found something high-value like a Vampire Squid or a Spider Crab.
Why You Shouldn't Just Mash the A Button
Most players hold down 'A' to swim and then mash it to go faster. Stop doing that.
Seriously.
When you're chasing the fast ones—the creatures that actually sell for over 10,000 Bells—mashing 'A' is actually your worst enemy. Why? Because the splashing alerts the creature. They have a detection radius. If you want to catch a Giant Isopod without a three-minute chase that takes you to the edge of the map, you need to sneak.
Use the Left Stick only.
Tilt it gently. Your character will do a slow breaststroke without splashing. You can get almost directly on top of the bubbles before you ever hit the 'Y' button to dive. This isn't just a "pro tip"; it's the only way to consistently catch high-tier loot without losing your mind. Once you’re underwater and right on top of it, then you lung towards it. It’s the difference between a 5-second catch and a 60-second marathon.
Understanding the Seasonal Shift
It's 2026, and by now, we all know the drill with the Critterpedia. However, people still forget that the ocean is more volatile than the land. The mix of creatures changes significantly between the Northern and Southern Hemispheres.
In the Northern Hemisphere, your summer months (June to September) are the golden era. This is when you’re pulling up the Gigas Giant Clam, which sells for a staggering 15,000 Bells. It’s the highest-priced sea creature in the game. But if you’re playing in the winter, you’re looking at a lot of Sweet Shrimp and Sea Slugs. Not exactly a gold mine.
Interestingly, the Spider Crab is a March and April exclusive for the North. It’s huge. It looks terrifying when you place it on your pier because it doesn't come in a tank—it just sits there on the wood, spindly legs and all. If you miss that window, you’re waiting another year or time-traveling, which some folks still consider "cheating," though at this point in the game's life cycle, who cares?
The Pascal Connection and the Pearl Problem
Pascal is the red sea otter who looks like he’s had one too many vacation juice drinks. He’s the philosopher of the sea. When you find your first Scallop of the day, he’ll pop up behind you like a jump scare.
A lot of people trade their scallops for Mermaid DIY recipes. That’s fine. But the real bottleneck in New Horizons isn't the recipes; it's the Pearls. Pearls are technically classified as sea creatures in the game's code, but they don't move. They have a tiny, tiny shadow.
The drop rate for Pearls while diving is abysmal. Roughly 1% if you're just lucky.
The smart move? Always give Pascal the Scallop. Even if you have all the furniture. He has a chance to give you a Pearl directly. Since you need those Pearls to craft the Mermaid set, and they sell for 10,000 Bells a pop if you’re desperate, Pascal is essentially a walking (swimming?) ATM. Just remember: he won’t show up if your gates are open or if your pockets are full. He needs space to give you your prize.
Breaking Down the "Big Three" Money Makers
If you want to maximize your time in the water, you have to ignore the small fries. Focus on the shadows that move. Specifically, these three:
- Gigas Giant Clam: It’s massive. It moves in huge, lunging bursts. It’s available from May to September (North). 15,000 Bells.
- Spider Crab: Available March and April. It’s fast. Very fast. 12,000 Bells.
- Vampire Squid: Found at night (4 PM to 9 AM). It has a quick, erratic movement. 10,000 Bells.
Notice a pattern? They all move. If a shadow is just sitting there, it’s probably an Acorn Barnacle or a Sea Star. Leave them. Unless you’re trying to finish Blathers’ collection, they are a waste of bag space.
The Museum is More Than Just a Checklist
Blathers has some of the best dialogue for sea creatures. The way he describes the Pearl Oyster or the Umbrella Octopus actually teaches you a bit of real-world marine biology. The exhibit itself is also arguably the most beautiful wing of the Museum. Watching the Moon Jellyfish drift in the glow of the tanks is a vibe that most other games can't replicate.
But don't just donate and forget.
The sea creatures you catch can be placed as furniture. Most go into tanks, but some, like the Sea Pineapple or the Horseshoe Crab, have unique interactions. The Horseshoe Crab, for instance, will flip over if you "interact" with it while it's placed on the ground. It’s a weird little detail that Nintendo didn't have to include, but they did.
Strategies for a Full Inventory
Inventory management is the hidden boss of Animal Crossing. When you’re diving, you don't want to keep swimming back to the shop.
Keep a storage shed on your beach. If you don't have the storage shed DIY yet (available after fully upgrading your house), use a trash can. It sounds counter-intuitive, but being able to dump "trash" creatures like Sea Grapes immediately without swimming back to shore keeps your "luck" streak going.
Also, wear a snorkel. It doesn't actually help you breathe longer—that’s a common myth—but it looks the part. The only thing that actually affects your diving is the wet suit itself.
Common Misconceptions About Diving
There's this rumor that's circulated since the game launched: "If you swim further out, you find better stuff."

That is false.
The spawn rates for sea creatures Animal Crossing New Horizons are tied to your island's "seed" and the current time/month, not your distance from the shore. You can find a Gigas Giant Clam two feet away from the sand. The only thing the "boundary" fence does is stop you from swimming to mystery islands or your friends' islands manually.
Another myth is that running on the beach scares away sea creatures. Unlike fish, which are sensitive to the vibrations of your footsteps, sea creatures don't "spawn" until you're in the water or at the very edge of it. You can sprint all you want on the sand without ruining your chances.
Actionable Steps for Your Next Session
If you’re looking to dominate the deep sea, follow this workflow:
- Check the Clock: Don't dive at noon if you want the big money. 4 PM is the sweet spot when the nocturnal, high-value creatures start appearing.
- Clear Your Pockets: Carry only your wet suit and maybe a ladder if you have high cliffs. Every extra slot is worth potentially 15,000 Bells.
- Sneak, Don't Sprint: Use the "no-splash" method with the Left Stick to approach bubbles. It saves time on the chase.
- Identify the Bubbles: Straight lines of bubbles mean fast movement. Sparse, wandering bubbles usually mean a slow or stationary creature.
- Farm Pascal Daily: Even if you hate the Mermaid furniture, those Pearls are essential for late-game crafting and trading.
- Use the Drop-Off Box: If Nook’s Cranny is closed, use the bin. You lose 20% of the value, but if your storage is full, it’s better than throwing money away.
The ocean in New Horizons isn't just a boundary; it's a massive, rotating inventory of wealth. By focusing on movement patterns instead of shadow size and mastering the "sneak" approach, you turn a tedious task into the most efficient way to fund your next bridge or incline project. Grab your suit and get in there—the Gigas isn't going to catch itself.
